I make the case that domestic military detention for all terrorism suspects isn’t necessary in this piece over at the Huffington Post. Legislative proposals by Rep. Buck McKeon (R‑CA) and Sen. John McCain (R‑AZ) would mandate military detention instead of criminal prosecution for all those suspected of international terrorism. I oppose this policy change for reasons both principled and practical:

If the civil rule of law handles terrorist threats adequately, then invoking military jurisdiction is a counterproductive overreaction.

That was the case with one of the handful of domestically detained enemy combatants, Ali al-Marri. Al-Marri was an honest-to-goodness Al Qaeda sleeper agent masquerading as an exchange student. The FBI indicted him on charges that could have carried a 115-year maximum sentence. The government requested that the judge dismiss its charges with prejudice, meaning that they could not be levied again, and moved him to a naval brig.

The Supreme Court ultimately agreed to hear al-Marri’s case, but the government mooted the case when it removed al-Marri from military custody and charged him with material support of terrorism. Al-Marri pleaded guilty and received a sentence of eight years and four months.

Al-Marri’s case was a missed opportunity. The government should have put him away for life.

This isn’t the first time McKeon and McCain have proposed treating all terrorism suspects like al-Marri and Jose Padilla. I criticized a similar proposal a year ago, as did Ben Wittes of the Brookings Institution. Wittes’ criticisms of this year’s bad ideas are here and here. Given the excellent track record of federal courts in prosecuting terrorism cases and the recent death of bin Laden, now is not the time to roll back the civil rule of law.
